Dual MAF wiring idea

The way to do it is kinda like this:

Splice into power from existing MAF plug, run this to power input on second MAF.

Splice into ground from existing MAF plug, run this to ground input on second MAF.

Plug wire into output terminal of second MAF, run this to the blue wire on your S-AFC.

Set S-AFC to use both sensors and sum the inputs.

The other two wires on the second MAF are NOT needed. I don't think it can get much more simple than that.

Sure you can try your idea, but the amount of work involved in doing it right is so small why not just do it? The above would probably take about 30 minutes, and the cost is exactly the same. I'll all for innovation to make things work better, or do it cheaper (the whole idea of dual MAFs), but not to avoid a extra half hour of cutting wires.

That and the air flow in each MAF might not be perfectly matched. Using each input is a sure way to make sure you are measuring air properly.

I might have not been too clear on my first post so I try to clarify. Consensus is to connect the power and grounds together and then send each air flow signal to the two inputs of the SAFC for summation.

Instead, I was wondering why not just send one air flow signal to both inputs of the SAFC for summation. Would end up looking like a Y.

Theoretically, if both sensors are functioning correctly, it shouldn't make a difference if the SAFC uses a signal from seperate MAFs or the signal from one. Just as long as you input a signal to both inputs of the SAFC to add them together.

I thought this would be a better idea since there would be no need to connect power and ground at all. And there would be no variance in signal from getting it from two difference MAFs. With one MAF functioning, less chance of one going bad and not knowing. The second MAF would just be sitting in the air intake path to allow for more volume to be drawn into the turbo. Air flow volumes should be identical and the air flow signal should be exactly doubled when summed.

So bottom line, the signal from one MAF would be input into both inputs on the SAFC. They get summed and the SAFC outputs the new signal to the ECU. What do you guys think? No need to connect the two MAFs togther electrically.
